The new FUor star HBC 722 - one year after the outburst

The first results from studies of the new FU Orionis star found in the field of NGC 7000 are presented in the paper. During the year passing from the registration of outburst at fourteen papers containing data from observations of this object have been published in the astronomical journals. These publications present photometric and spectral observations of HBC 722 ranging from the far infrared to X-ray wavelength region. HBC 722 is the first FU Orionis object, whose outburst was observed from its very beginning in all spectral ranges. We expect that the interest in this object will increase in the coming years and the results will help to explore the nature of young stars.

The FUor Candidate V582 Aurigae: First Photometric and Spectroscopic Observations

One of the most attractive events in the pre-main sequence evolution is the FU Orionis (FUor) outburst. Because only a small number of FUor stars have been detected to date, photometric and spectral studies of every new object are of great interest. Recently, a new FUor candidate was discovered by Anton Khruslov - V582 Aur. To confirm the FUors nature of this object we started regular photometric observations with the telescopes of the National Astronomical Observatory Rozhen (Bulgaria). A high-resolution spectrum of V582 Aur was obtained with the 1.93 m telescope in Haute-Provence Observatory (France).
